APPARATUS FOR DYEING SKEINS.

Application filed January 4-, 1910.

To all whom it may concern:

Be it known that we, JUAN Rnoonnosn and LUIS Bneonnosn, manufacturers,subjects of the King of Spain, residing at Barcelona, in the Province ofBarcelona and Kingdom of Spain, have invented certain new and usefulImprovements in Apparatus for Dyeing Skeins; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in apparatus for dyeing skeins, inwhich the skeins are arranged in continuous rows and are passed throughthe baths steadily.

The object of the present invention is to separate the threads of eachskein as it enters the bath, thus forcing the liquid to circulatebetween the threads, which results in a more uniform and satisfactorydyeing of the same.

Other objects will appear in the detailed description.

In the accompanying drawings-Figure 1 is a section of a portion of anapparatus adapted to carry out our invention, taken on the line 11 ofFig. 2. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3is a horizontal section, looking downwardly, taken on the line 33 ofFig. 1, with the chains and the skeins removed. Fig. l is a horizontalview, showing the mechanism for producing alternate oscillations of thechains. Fig. 5 is an end view thereof. Fig. 6 is a plan view of amodified form for producing the same movement. Fig. 7 is an end view ofthe parts shown in Fig. 6. Figs. 8, 9, and 10 are vertical sectionalviews of a part of a machine, with various forms of mechanism foragitating the liquid.

The dyeing operation is carried on in vats such as f, Along the sides ofthese vats are parallel rails r, on which is mounted the skein carryingpart of the apparatus, being supported on rollers 79, whereby the wholeapparatus may be easily moved from one vat to another to take advantageof the difi'erent baths, when desired. On these rollers p is mounted aframe, preferably triangular in Specification of Letters Patent.

form, which supports the shafts and other means for 110] d1ng thetraveling chains.

0 represents the traveling chains, of which 7 there are two, arrangedparallel with each other and furnished at intervals with spring clips 6.In these clips cross pieces 6 are adapted to be slipped, carrying theskeins a, and the cross pieces 6 are united by elastic connections 6 inorder to keep them in place. The clips 6 on the chains are arrangedparallel to each other, so that practically the whole space between thechains may be filled with skeins, as indicated on the lower part of Fig.2. These chains run at the bottom over supporting rollers cl, (Z and (Zmounted in a triangular frame. This frame includes horizontal crosspieces h and vertical guiding rods 71. which engage with grooved rollerst carried by the main supporting frame, so that the entire framesupporting the rollers (Z, (P, and (Z may rise freely, being guided bythe four rollers 25, and tends to return to its normal position, asshown in Fig. 1, by its own weight. At the top, the chains 0 run overrollers 0 supported in suitable bearings in the main frame 28, andbetween these rollers, though .on a lower plane, is arranged a shaft 14provided with weights M The shaft 20 is loosely supported in slots inthe uprights '2), carried by the main triangular supporting frame 28.Any suitable means may be employed for causing the chains to travelcontinuously into and out of the bath in the vat On the shaft 10 rollers11, are mounted, under which the chains 0 pass. The combined weight ofthe parts if, the shaft 24 and rollers u is suilicient to counterbalancethe weight of the chains 0 and parts carried thereby. As the chains 0emerge from the bath, the skeins pass between squeezing rollers z andbetween brushes j, which have both a rotary and a reciprocatorymovement. The rollers z and brushes 7' are for the purpose of preventingdripping.

As the skeins enter the bath, they are agitated in the following manner:a represents a roller bearing against the slrcius and mounted on asuitable shaft 29, which shaft has enlargements 2 engaging the chains 0.

The roller .2 is agitated in the following manner Its supporting shaftis supported by arms 9 loosely mounted on a fixed horizontal shaft g,and the parts 9 are also connected to curved arms 9. 70 represents adisk driven by any suitable motor (not shown) and having on it a crankpin 30 to which is fixed an arm 70 which bears on its end a roller 31engaging a slot 82 in the benta-rm g. By this connection, itis obviousthat the rotation of the disk 70 will swing the roller 2 and the chains0 in a substantially horizontal direction. To make the movement moreeffectual, another roller :2: on the inside of the chains 0 ispreferably employed, which is supported on arms x pivotally mounted on apart of the main supporting frame 28. Links m connect the supportingarms g with the supporting arms m so that the rollers .2 and :0 will bevibrated in unison.

Pivot-ally connected to the crank pin 30 on the disk 70 is an arm Z, theupper end of which is connected to a bent arm m, which arm is in turnconnected to the shaft n of the rocker a which is pivoted between theends of the shafts 83 and 34 carrying the brushes j, so that by theconstruction just described the brushes will have a reciprocatorymovement in opposite directions. These brushes are mounted to runloosely so that they revolve by the motion of the chains. They comb outthe threads, part them from each other, and leave them quite seaaratedand almost dry.

In order to increase the eiiiciency of the movements of the skeins inthe liquid, the roller (Z is reciprccated longitudinally by thefollowing means: On one of the rods h is secured a bracket 35, in whichis pivotally mounted a lever 0, which is located between the shaft 36 ofthe roller (Z and the shaft 33 of one of the brushes j. It is providedwith forked ends, which engage in recessed collars on these shafts.

The operation is as follows: The skeins a being stretched upon thechains 0, these are united by the elastic bands 5 and slipped into thespring clips 6. The chains 0 are then set in motion, by any suitablemeans, and the skeins are carried first downwardly into the bath, thenacross over the rollers (Z, (Z (Z and then up between the squeezingrollers 2' and the brushes this operation being repeated as often asdesired. As they pass downwardly into the vat the chains carrying theskeins are reciprocated back and forth, thus agitating them and insuringa thorough dyeing of the threads thereof; Then as they pass over therollers (Z, (Z and (Z they are bent and therefore subjected to tension,which tends to spread the threads and insures that any undyed portionshall be saturated. After passing through the squeezing rollers 2' toremove the excess of dye, the skeins are combed and the threadsthoroughly separated by the rollers j, and this operation being repeatedas often as desired insures that every thread,'and each part of everythread, shall be thoroughly impregnated with the dye.

Any means for producing relative motion between the dye liquor and theskeins as they are passed through it may be used, as shown in themodified forms, Figs. 4 to 10. F or example, the rollers .2 could bereciprocated in the direction of its axis, if desired. Furthermore,alternate movements in op posite directions of the parallel chains couldbe produced so as to produce a semicircular movement of the skeins. InFigs. 1 and 5, an arrangement for producing this movement isillustrated, and in this modification a bar 4: is placed behind orinside the skeins, carrying a roller 9, opposite one chain, and a bar 7,parallel to the bar l, is placed in front or on the outside of thechains, carry ing a roller 8, opposite the other chain. The bar 1 ishung from the shaft 1 by means of links 3, and the bar 7 is hung fromthe shaft by links 6, the links being connected by rods 2, one end aboveand one below the point of suspension, as shown in Fig. 5. The result ofthis construction is that as these parts are swung back and forth, asalready described in connection with the rollers x and 2, the roller 8pushes one chain out of line, while the roller 9 pushes the other chainin the opposite direction, producing a semicircular movement of thechains. In Figs. 6 and 7 is illustrated another form for producing thisagitating movement. In this modification, an oscillating arm 10 rocks anarm 12, which by means of a connection 17, carries on one end thetrunnions or bearings of the rollers 15 and 16. A second shaft 11,oscillating in the opposite direction, has an arm 13 connected thereto,which arm carries a shaft 14, in which are located the other bearings ofthe ends of the rollers 15 and 16.

Instead of agitating the chains carrying the skeins, the liquid in thebath may be agitated, or both the liquid and the chains may be agitated,if desired. In Fig. 8 is shown one means of agitating the liquid, inwhich the rollers ac and .2, shown in Fig. 1. are replaced by horizontalpaddles 1S and 19, the oscillatory movement of which forces the dyeingliquid through the skeins carried by the chains 0. The paddles 18 and 19are mounted on arms 20 and 21, pivotally mounted on shafts 22 and 2-3and connected together by links 2st, the whole being operated by thecurved arm g, moved by the arm or rod 7e, pivotally connected theretoand to a crank pin 80 on the revolving disk 70. In Fig. 9, still anothermeans of agitating the liquid is shown, consisting of shafts 25,

provided with paddles 26, which are revolved by cords or belts 27,driven by the disk in.

In the modification shown in Fig. 10, the paddles are dispensed with andthe liquid agitated in the following way: 28 represents pipes located onopposite sides of the chains 0 and each provided with a series of smallopenings directed toward said chains. A pump (not shown') sucks in theliquid and forces it through the pipes 28 in the form of a series ofjets thrown against the skeins a carried by the chains. After the dyeingoperation in one vat, f, has been finished, the frame carrying therollers (Z, (Z, and (Z is raised above the top of the vat, sliding onthe pulleys t, and the whole ap paratus may then be moved over anothervat f containing, if desired, a different dyeing liquid. The frame isthen allowed to fall to the position indicated in Fig. 1 and the dyeingoperation continued in the vat f, as already described.
